The portablepower plant comprises an internal combustibneng-ino ill having a crankcase- HJ, cylinder l2: and a base portion- 13', preferably constructed as an integral partof the crankcase. A pair of angle'bars l5 are secured to the engine base, and as seen more clearly in Figs; 2 and 3, these angle bars are secured by view taken on the bolts l6, and to bosses IT carried by the engine base. a r

A housing 2E1: encloses the engine l0, same bei-ng; cutout for the fuel tank: 21 and for the air cleaner 2.2,; The end walls of the housing are cutthe underside of these sid rails.

The. same bolts which. secure. the side. rails 0.1: ans-1e bars 15. to theena nebase 1 3. are mployed to secure the h using. to the, engine. ase, and these: bolts are. alsothes le. mean for attafihs ing the housing to saidengine.. Asmore. cl arly shown: in Fig;- 2... it.- will be observed ha the right. hand side. wall 2M overlaps. the v rtical flange of. the anglebar and i provided with hol s. in; iegistration with. the. holes in thev angl a to receive the, bolts 15. The. opposite side Wall. 183 of the housing s also iastenedto the eng n basoby, bolts to.

Those side rails, which; 'suhhort the. engine and; which, may bebroadly rcferredzto as frame-mem hers compri e angle barsand the. horizontalflangeof.- b th b rs are provided. with elon ated slots. 25,- extending' longitudinally ofthe bar. The le bar; is convenient y provided, wi h a pl rality of these elongated slots (see Figs. 3 and 4) and a pain of resilient supporting devices C0rn-.-. prising rubber plugs 2,6 are secured by bolts 21 in the end slots of each, angle ban and func-. tionto elevate the engine and hQllSlIlg assemhz'from theiloor.

These.- resilicnt supports one prefer ly rywidel n spac d along. the' bar. andspresently spaced serve to bar creeping of the power plant; during engine operation. These resilient supporting devices. are adjustably secured to the-side rails and thus can. be. selectively paced to secure. the po -plant ag inst epi aocessory mount ng plate 36 i ecured to. he p ate is substantially triangular, and the base side on: clothes these two. side rails and the engine base,v bolts 3! securing the plate to the side rails. The plate is provided with an opening 32 through which one of the resilient supporting devices 26 project; said plug serving as a. pilot to position the plate. An accessory or other machine. 35 is mounted on this plate 30 and is driven by said engine. 1

In the drawing; 1 have illustrated a. grinder tool, and bolts 3& cooperating with the slots; 31' secure this tool to the base, said slots providing for adjustably positioning this tool for proper belt tension.

It will be seen that I have provided a very compact unit and said powerplant is well bal-v aneed the two hand gripsbeing; substantially equally spaced from the center of gravity.- and substantially diametrically opposite. The boxlike housing is constructed quite rigid and the side walls 20A and 20B are each secured at two fairly widely spaced points to the engine base and on lifting the power plant by these hand grips it will be observed that the weight of the engine is substantially uniformly distributed.
